Nº.4 Bond Maintenance Shampoo

$30.00In Stock

Every wash is either building bonds or breaking them. Olaplex No.4 does both — cleanses while the patented bis-aminopropyl diglycol dimaleate reconnects the broken disulfide bonds that make hair fragile. For color-treated, bleached, relaxed, or heat-damaged hair. Non-negotiable if you're doing any chemical services.

Ingredient Spotlight

Bis-Aminopropyl Diglycol Dimaleate→Olaplex's patented bond builder — works during the cleanse, not just treatments.

Sodium Lauroyl Methyl Isethionate→Gentle surfactant — cleanses without stripping already-compromised hair.

Panthenol→Adds moisture and flexibility — balances the protein-heavy bond repair.
